Prep: Preheat oven to 425°F (220°C). Line 2–3 large sheet pans with parchment paper.
Mix Veggies: In a large bowl, toss potatoes, peppers, zucchini, and onions with half the olive oil, half the salt, and half the herbs/spices.
Season Chicken: In another bowl, toss chicken with remaining olive oil, salt, and herbs/spices. For a spicy batch, toss half the chicken with Cajun seasoning or cayenne; keep the rest mild.
Arrange: Spread veggies and chicken in a single layer on sheet pans, keeping spicy and non-spicy chicken separated.
Roast: Bake for 20–25 minutes, stirring halfway, until chicken is cooked through and veggies are tender.
Serve: Transfer to a serving platter. Garnish with parsley/cilantro and lemon wedges. Offer extra Cajun seasoning or hot sauce on the side for those who want more heat.
